KARL MEYER-GAUS, OF BARMEN, GERMANY, ASSIG-NOR TO THE FIRM: AMERICAN BEMBERG CORPORATION, OF YORK, N. Y.

SPINNING OR DOUBLING EPINDLE.

Application filed April 6, 1927, Serial No. 181,447, and in Germany April 10, 1926.

This invention relates to a stopping device for spinning or doubling spindles, and more particularly for such spindles with oil projecting flanges on the whirl.

According to the invention, the oil pro jecting flange forms at the same time the brake flange, the flange being such that a cap mounted on the outer wall of the oil collecting chamber by means of a screwthread can be pressed against the said projecting flange by turning the said cap.

1n the case of flyer spindles it is known to use for the purpose of regulating of the speed difference between the bobbin and the flyer, a brake in which a cap is screwed on a brake ring. In that case however it is a question of a separate brake ring to which the bobbin is connected by a claw coupling This brake ring rotated in a lubricant container which was screwed on the braking cap so that it could be pressed more or less strongly against the brake ring by turning.

The device according to the present inven tion differs from this well known arrangement by the fact that the already existing oil projecting flange is utilized as the brake ring so that a separate brake ring and claw coupling are dispensed with. In the same way the already existing oil collecting chamher is utilized for mounting the braking cap. It is therefore a question of fitting a brake device known in itself, to a spinning or doubling spindle with an oil projecting flange. Moreover the invention relates to a stopping device, whilst the well known device relates to the regulation of the doubling.

A spindle according to the invention shown in the accompanying drawing, in

Figure 1 in Vertical section in Figure 2 in lan.

The spindle has a belt drive. The oil contained in the spindle bearing sleeve 1 is drawn upwards into the neck bearing 3 by the rotation of the spindle 2, and if there is too much oil in the spindle bearing sleeve, it passes partly into the bell shaped hollow chamber of the driving whirl l, along the inner wall of which it descends and obtains access to the projecting flangeb from which it is projected into the oil collecting cha1nher 6 of the bearing sleeve 1. It can then return to the lower oil chamber at the lower end of the spindle 1 through bores 7.

The oil collecting chamber at the lower end of the spindle is closed by a cap 8 which is used also for holding down the spindle. The cap 8 is screwed on to the head of the bearing sleeve, containing the oil collecting chamber. The belt driving the spindle is market 13, and the spindle frame 14.

According to the invention, the cap is formed into a brake which acts in the axial direction on the driving whirl or on its projecting edge 5. The braking pressure can be produced in various ways, preferably by screwing the cap down on to the bottom part of the spindle. It is preferable to provide a leather washer 10 between the projecting edge and the braking cap. The turning of the cap is effected by means of the handle 11.

that I claim is:

1. A stopping device for spinning doubling or twisting spindles comprising a flange on the spindle a hollow member surrounding said flange and a cap rotatably and axially movably mounted on said hollow member, the cap being able to be pressed by turning against the flange.

2. A stopping device for spinning doubling or twisting spindles comprising an oil projecting flange on the whirl of the spindle, an oil collecting chamber surrounding said flange and a cap mounted by means of screwthread on said chamber, said cap being able to be pressed by turning against said flange.

In testimony whereof, I, KARL MEYER- GAUS, have signed my name to this specification this 18th day of March, 1927.

KARL MEYER-GAUS.
